通过从点源收集和液化温室气体二氧化碳,并在适当的位置和足够的深度将其泵入海洋,可以加速海洋对温室气体二氧化碳的自然吸收。数值模拟系统的结果表明,位于挪威东部约 1,000 米深度的注入点可在大西洋深渊中实现有效且长期的封存。对于相当于 220 MW 燃气发电厂 CO2 排放量的释放率,发现 pH 值降低≥0.1 的近源水体积约为 0.5 km3。这些发现,加上现有技术和可行的经济学,表明挪威海可能是大规模示范海洋二氧化碳排放的可能地点。
The natural ocean uptake of the greenhouse gas CO2 can be accelerated by collecting and liquefying the gas from point sources, and by pumping it into the ocean at appropriate locations and at sufficient depths. Results from a numerical modelling system indicate that injection sites located at about 1,000 m depth in the eastern Norwegian Sea lead to efficient and long term sequestration in the abyss Atlantic. For a release rate corresponding to the CO2 emissions from a 220 MW gas power plant, it is found that the volume of the near‐source water with a pH‐reduction ≥0.1 is ∼0.5 km³. These findings, together with available technology and feasible economics, indicate that the Norwegian Sea represents a possible location for large scale demonstration of operational ocean release of CO2.
